EDDY CURRENT INSPECTION

With its roots based in electromagnetism, eddy current inspections are now a widely used and well understood inspection technique for flaw detection, as well as thickness and conductivity measurements. To detect material flaws with this technique, Cadorath’s technicians use a single-element eddy current probe—a coil of conductive wire which is excited with an alternating electrical current. Defects cause a change in the eddy current and a corresponding change in phase and amplitude.

 

ADVANTAGES OF EDDY CURRENT INSPECTION

  • Versatile and applicable to a wide range of materials.
  • Because of its electrical nature, the process is limited to conductive material.

 

ORIGINS AND DEVELOPMENT

Léon Foucault is credited with discovering eddy currents in 1855 but the process started being used in industrial applications as a result of the English scientist Michael Faraday’s experiments.

 

FUTURE APPLICATIONS

The process requires ferrous alloys to be effective, thus leaving little to no room for experimentation with other materials or applications.
